Personally, I leave my strings pulling until my WISE stops chattering (which is normally a couple of seconds after the beep).

I would say i'm a slow weaver on the crosses, but i leave the wise tensioning like you do, but on every other cross when i weave 1 cross ahead. The other times i clamp and disengage the wise, flip the racket 360 (because the handle is obstructing me from weaving ahead during tension) and weave 1 ahead. That should negate the tension loss theory.

I'm excited about your work. Can you explain how you ping the rackets to measure the frequency? I use Carltunbe, too and knock with the frame of another racket against the stringbed. Maybe their is a difference?
I did this morning a 29 / 31 BG65 (10 % prestretched, proportional stringing for the cross) on one of my MX80 and measured only 1267 Hz directly after stringing. Maybe I'm too stupid to measure correctly or my jobs are really off.

My method of measuring the frequency is exactly the same as yours. Ping the stringbed against the frame of another racket. I only started recording frequencies in to my database this year. I don't think 300+ data points is sufficient since some tensions are for only one string job. It's best to go with the average frequency for now and not the extreme min and maxes. I'll probably generate a new report at the end of the year when i have a larger sample size.

Right now i can't make any conclusion about my data or anyone else's simply because there are a lot of variables: racket frame, constant pull (on/off), prestretch, supports, the stringer. I hope with time and larger sample size, the average frequency will be my "target" for consistency.

Generally speaking if we come to conclusion that the frequency is a dimension to measure string tension their shouldn't be so much differences otherwise this method is muck for measurements. So IMO their is a need for same conditions like same racket frame, same analyzer, same room, same main/cross ratio, same modi for the wise, identical machine and so on.
I think that there is no frequency that tells you the exact tension. IMO I'm really off with my measurement, maybe we are all wrong.

My default setup:

PS3600 with a wise, fixed clamps, 10% PS, Chudek supports.

My 29/31 job is a bit below of DarthHowie 27lbs job, if we use the frequency as reference. So I'm nearly 100 Hz of which is for my sight of view a huge difference and I don't think I do a worst job. I can't help but this measurement makes me crazy. Maybe this fixating on frequency is a dead end until we have the same equipment and same procedure to measure tension.

I've been mainly using the frequency data as a reference to what a comparable tension frequency wise would be needed should my customer want to use a different string...(I'm aware the material of the string and its use: power vs control or hard vs soft will not make it an apples to apples comparison). At least recording the stringbed frequency is a great way of measuring tension loss which is something i definitely care a lot about.

I figured maybe this is something of added value a stringer can provide to all levels of players when they get the common question "What string and tension do you recommend for me to put on my racket?"

The BG65 results are quite a ways lower @ 22 and 20 from the chart on pg. 13. I doubt my stringer is deliberately stringing it lower than requested so there does seem to be a fair margin of difference?

Although, I did use a guitar pick to measure so I'm not sure if that changed the reading some.

So my frequencies are good deal lower than some others here, which is kind of weird because my tensions are quite equal to some rackets I strung (and got strung) at tournaments.

When I put my Adipower bg80 (29/30) aside for a weekend I saw the tension drop 5.5% in 24h (1185Hz), and 6.1% after 56h (1177Hz) (3 days unplayed). Is that good or bad?

I think the more important thing as a stringer is to make sure your tensions/frequencies are consistent. From replies in the forum..my initial frequencies are higher than most stringers. I warn new people i string for that my tensions feel about 1 pound more than others. I'm wondering if that's because i pull 10% more on the crosses...so 29 pounds for main...+2.9 pounds for cross. so 29 x 31.9. That may explain why it is higher.

The chart i attached a while back is probably out of date now that i have more data points. My goal is to hit the "average frequency" for each tension and string combo. The Highs and Lows are for me to keep track of the extremes. I do notice that i get consistent frequencies for the same model racket, string and tension...and there is more variance once i introduce a different racket model. Maybe it's materials.

Just want to repeat that the chart is more a guide for myself. I just hope it serves as a bit of a reference for others in the community. I will try to publish a more up to date one.
